KLayout 0.29.5 (32-bit)

What's new in this version:

Features:
Fixed:
- Spice throws error at midline semicolon comments
- Instantation path highlight mismatch with view window
- Change "angle constraint" of box and ellipse ruler templates to "any angle" by default
- Can't set cell properties by script
- MetaInfo with (gigantic) size makes klayout write a faulty gds
- inconsistent results in width_check when calling by keyword argument
- Internal error on "nan" values in PCells
- Small bugfix: 'Delete selected stacks' was not working from stack tech component editor's context menu
- Including more GeneratorExit and StopAsyncIteration in the ignored exceptions for Python.
- Properly transferring ownership for variant to Python/Ruby translation.

Enhanced:
- Support for recursive PCell instances
- Undo/redo from List
- Marker Browser: make the state of the "By Cell" or "By Category" tree persistent
- GDS2 writer now observes limitations of the file format
- and raises more errors on value over- or underflows. This should specifically avoid issues writing certain large arrays which are legal inside KLayout, but illegal in GDS2.
- Trying to improve "grab" behavior of partial selection.
- In certain situations is was difficult to grab the partial selected edges. Instead other edges would be selected. Now, it is enough to click inside the bounding box of the partial selection.
- These exception now do not make the debugger stop any longer.
- This is required for some Python and Ruby bindings, when objects are transferred through generic arrays.
- Added Region#being_shapes_rec and Region#begin_merged_shapes_rec.
- Mainly for being able to retrieve shapes with properties from Region#nets
- Convenience methods Shape#properties, Layout#properties, Cell#properties, Instance#properties.
- These method will obtain all properties as a hash.
- Added Netlist#top_circuit and Netlist#top_circuits convenience methods.
- These methods will deliver the single top circuit or a list of top circuits.
- "Copy cells" now has an option to mute the dialog (shallow/deep)
- and the dialog is only shown if there are subcells
- Added Shapes#break_polygons, Layout#break_polygons, Region#break_polygons.
- These methods split large polygons into smaller pieces.
